Sistemas de enfriamiento de agua

La tecnología de enfriamiento de agua 3D TRASARTM de Nalco Water puede detectar variabilidades en el sistema, determinar la respuesta correcta y darle eficiencia a la operación y el costo. This has enabled fabs to use reclaimed process rinse waters as cooling tower make-up and, in certain cases, eliminate the use of fresh water for cooling towers - all with assured asset preservation.

Más beneficios del programa de agua de enfriamiento de 3D TRASAR:

  • Less energy with scale and fouling prevention
  • Reduced water with increased cycles of concentration
  • Real-time system data via performance dashboards
  • Assurance that system experts are watching your system 24/7
  • In one customer’s operation, 1.2 billion gallons of water were saved in five years with no loss of chiller performance in 17 years
  • In another, 73 million gallons of water were saved in the first year, with over $1.7 million in reduced Total Cost of Operation (TCO)

Seguridad e higiene de agua

From Legionella testing and inspection of cooling towers to cleaning & disinfecting and the certification supporting a cooling tower water management plan, our Water Safety Protocol provides a complete water safety solution:

  • Legionella testing – Nalco Water conducts more Legionella analysis than any other organization in the world. We are global experts in water safety with over 25 years of experience.
  • On-line Tower Disinfection – Highly trained and certified Nalco Water service engineers will disinfect the operating cooling water system over a six-hour period, and then safely return the system to normal operating conditions.
  • Off-line Tower Disinfection – Certified Nalco Water service engineers complete a full physical cleaning of the tower decks, fan housing area, distribution nozzles, tower fill and water sump.
  • Inspection and Certification – Nalco Water is certified according to guidelines published in the OSHA Technical Manual (Section III: Chapter 7, Legionnaires’ Disease).
  • Having developed and implemented over 10,000 cooling tower water management plans globally, Nalco Water can help you develop a water management plan tailored to your operation and compliant with ASHRAE Standard 188.

Capacidades de apoyo analítico

Nalco Water's Global Analytical Support enables faster, more thorough troubleshooting and problem resolution. Examples of laboratory support include:

  • Water analysis (UPW, PCW, Wastewater, Cooling Water, Reclaimed Water);
  • Microbial analysis;
  • Deposit analysis;
  • Failure Analysis (metallographic);
  • Reverse Osmosis Membrane autopsies; and
  • Corrosion coupons.

These types of analysis can help fabs make better decisions faster on topics as diverse as:

  • Resolving production-impacting PCW issues.
  • Reclaiming new water sources as cooling water make-up, reducing water consumption and water footprint.
  • Optimizing RO system performance.
  • In one case, Nalco Water’s lab support helped a customer identify the source of a PCW contamination issue and facilitated the customer task force’s ability to quickly narrow its focus and find and eliminate the problem.
